Modules for LIS : SD,MM, PP,QM.

Deltas for LIS:
After setting up the LIS environment, 2 transparent tables and 1 extract structure is generated for this particular info structure. Within transaction SE11 you can view the tables ‘SnnnBIW1’, ‘SnnnBIW2’ and the structure ‘SnnnBIWS’ and the InfoStructure itself ‚Snnn‘
The tables S5nnnBIW1 & SnnnnBIW2 are used to assist the delta update process within BW.
Extract structure ‘SnnnnBIWC’ is used as an interface structure between OLTP InfoStructure and BW
The OLTP system has automatically created an entry in the control table ‘TMCBIW’. Within transaction ‘SE16’ you’ll see, that for your particular InfoStructure the field ‘BIW active’ has the value ‘X’ and the field ‘BIW status’ is filled with value ‘1’ (refers to table SnnnBIW1).
The orgininal LIS update program ‚RMCX#### will be enhanced within the form routines ‚form Snnnbiw1_update_....‘ and ‚form Snnnbiw2_update
With the transaction ‘SE38’ you’ll see at the end of the program starting at line 870 / 1006, that the program is enhanced within a ‘BIW delta update’ coding
Within the flag ‚Activate/Deactivate‘ the update process into the delta tables (SnnnBIW1/Sn5nnBIW2) is swichted on/off. In the table ‚TMCBIW‘ is defined, which table is active for delta update.
Note: The delta updating is client dependent !
